GlassFish Developer FAQ

This Developer FAQ lists frequently asked questions related to the development of the GlassFish application server and is for developers contributing bug fixes, new code, and other improvements to Project GlassFish. For FAQs related to the use of GlassFish and general questions about GlassFish itself, see the GlassFish User FAQ.

In true wiki and open source fashion, this Developer FAQ is a community effort. Help fill in the blanks, add new FAQs, and generally make this a valuable resource for you and other GlassFish developers.

This is a community resource. The success and usefulness of this FAQ depends on you. Please help by contributing new FAQs and updating and enhancing existing ones.

How to Contribute

For starters, add new FAQs of your own and enhance and update what's already here. This is a work in progress and your contributions are definitely needed. Be sure to read How do I contribute to this Developer FAQ?, which contains guidelines about content and format. Nothing too restrictive, just some things we should all pay attention to. Also check back periodically to see if you can answer any of the questions listed in the Developer FAQ Wish List section.

If you're new to wiki, see the One Minute Wiki and Text Formatting Rules. To test things out, try the Sand Box. And as always, remember your Wiki Etiquette.

If you have questions or suggestions about this FAQ, please contact docs@glassfish.java.net. You can subscribe to the list from the GlassFish mailing lists page.

Translation into other languages is also needed. See Translating User and Developer FAQs for details. The full Developer FAQ is currently available in Japanese. Translation into Italian is also underway.
